Description
Product Overview
The SDO 3411 Relay Output Module from Triconex delivers fault-tolerant digital output for safety-critical systems. Built for Tricon Systems, this module features 16 isolated output channels designed for emergency shutdown and process protection.
Each channel in the SDO 3411 includes three independent output circuits that participate in two-out-of-three voting logic. This Triple-Modular Redundant (TMR) architecture ensures uninterrupted operation even during component failures.
The module supports hot-swappable functionality, allowing technicians to replace units without halting operations. Its 24VDC output rating covers most industrial actuator requirements, including solenoid valves and motor starters.
Comprehensive diagnostics continuously monitor output health and wiring integrity. The SDO 3411 maintains synchronization across Tricon controllers' three parallel processing paths, ensuring consistent and reliable performance.
